Updating root.hints or named.ca file

From our own experience, not many folks keep up their named.ca or root.hints file for the DNS service. Fetching this file every month is recommended if you run a busy recursive DNS service, for example, an ISP provider DNS or medium to large corporation DNS servers.

You can easily fetch this file with a dig utility:

dig @a.root-servers.net . ns > root.hints

or

dig @a.root-servers.net . ns > named.ca

You can easily set-up a crontab entry to perform file update.

Enjoy!
